TRAVELER Filed April 10, 1937 741 mam/E11 AT ORN 5 Patented Mar. 22, 1938 UNITED STATES PATENT OFFICE TRAVELER Application April 10, 1937, Serial No. 136,101

5 Claims.

This invention relates to ring travelers for spinhing machines.

Ring travelers when in operation on a spinning machine travel at a very fast rate of speed around the ring and when so traveling the traveler floats or has practically no contact with the ring.

Various travel cross-sections have been proposed and used, such for instance as round, flat and half -ova1, that. is oval on one side and flat on the other.

This invention has for its salient object to pro vide a traveler so designed as to cross-section as to reduce the friction of the yarn on the traveler to a minimum.

Another object of the invention is to provide a traveler having a cross-section so designed as to reduced to a minimum the air resistance on the traveler.

Another object oi the invention is to provide a traveler so designed as to cross-section as to equalize the weight, thereby producing a more periect balance.

Further objects of the invention will appear from the following specification taken in connection with the drawing which forms a part of this application and in which Fig. l is a sectional elevation of a traveler ring having mounted thereon one form of traveler constructed in accordce with the invention, and

Fig. 2 is an enlarged transverse sectional ele-= vation of the traveler.

in the embodiment of the invention illustrated in the drawing there is shown a'traveler it which may be of any desired form or shone and in the form illustrated has hooks. ii and it iorrned on the ends thereof for embracing the spinning ring l l. The yarn Y is shown as leading downwardly to the ring Ill, passing under the angular portion ill of the ring and being led to the bobbin or spool S.

The particular novel lecture oi the traveler consists in the cross section which is shown in the enlarged view in. Fig. 2. From this figure it will be noted that the surfaces and ti oi the traveler are curved or conven and meet at edges it and in lines which lie in the plane oi the major aids the cross-section. will also be noted the central portions and ti oi the cross-secticn'ai'e lint.

The yarn annrcrnhes the traveler irorn an angle and engages one oi the convert surfaces or ill and passes around and across the flat surface it or it, leaving the traveler curved or convet. adjacent other edge oi traveler,

(Cl. 118--61l 7 There is a minimum amount of frictional engagement between the yarn and the traveler, and furthermore the air resistance to the movement of the traveler around the ring will be reduced to a minimum. Moreover, the traveler is symmetrical with reference to the major axis which passes through the meeting points of the oval or curved portions 20 and. 2!.

If desired, the edges of the traveler or ends of the oval surfaces shown at 23 and 24 may be slightly rounded instead of sharp.

Although one specific embodiment of the invention has been particularly shown and described, it will be evident that modifications and changes in the construction may be made without departing from the spirit and scope of the invention, as expressed in the following claims.

Having thus described my invention, what I claim is:

1. it ring traveler having means for embracing a traveler ring and having a double convex cross section at the edges of the traveler, the central portions oi the cross section being flat, the cross section being symmetrical with reference to a line passing through the two edges.

2. A ring traveler having means for embracing a traveler ring and having a double convex cross section at the edges of the traveler, the central portions of the cross section being flat, the cross section being symmetrical with reference to a line passing through the two edges.

3. A ring traveler having means for embracing a traveler ring, said traveler being not at the central portion of the cross section and curved at the outer ends of the cross section. the cross section being symmetrical with reference to a line passing through the two edges of the traveler.

i. A ring traveler having means for embracing a traveler ring, said traveler being ilat at the central portion of the cross section and curved at the outer ends of the cross section, said curved portions meeting at the two edges in lines and being symmetrical with reference to a line pas... ing through the two edges.

5. ii. ring traveler having means for embracing a traveler ring, said traveler being flat at the central portion oi the cross section and curved the outer ends oi the cross section, said curved portions converging toward the edges of the trov eler and being setrical with reference to a line passing through the two edges oi the trov eler. y
